    • mn10300.h (RETURN_ADDR_RTX): Define. · 74452ac3 
              * mn10300.h (RETURN_ADDR_RTX): Define.

        * mn10300.c (count_tst_insns): New function.
        (expand_prologue): Load zero into data and/or address registers
        if any are free and the function has optimizable tst insns.
        (output_tst): If a suitable register is known to have the
        value zero, use it instead of searching for a suitable register.
        * mn10300.h (zero_dreg, zero_areg): Declare.
        (FRAME_POINTER_NEEDED): Frame pointers are not needed if the
        outgoing argument size is zero.
        * mn10300.md (movXX): Optimize loading zero i        register if possible.  Optimize loading a DF/DI mode value
        into an address register from a constant memory address.
        (addsi3): Provide alternative which doesn't require a matching
        inout operand.
        (return): Optimize consecutive return instructions.

    • (incscc): Use a match_operand with cc_register to match the condition code register. · f54fd62e 
      (incscc): Use a match_operand with cc_register to match
the condition code register.
(decscc, *condbranch, *condbranch_reversed, *mov_scc): Likewise.

(andsi_not_shiftsi_si): New insn.
(*minmax_arithsi): Don't match this insn if operand1 is an
eliminable register.
({sin,cos}*): Delete, since the ARM always emulates these its
faster to call a library function.
(movsicc, *movsicc_insn): Make operand0 an s_register_operand,
and operand3 an arm_not_operand.  Use cc_register to match the
condition code register.
(mov[sd]fcc*): Make operand[0,2] s_register_operands, and operand3
the nonmemory_operand.  Use cc_register to match the condition
code register.
(*ifcompare_plus_move): Move before *ifcompare_arith_move.  Just do
a split for the output.
(*ifcompare_move_plus): Similarly, but relative
to *ifcompare_move_arith.
(*if_plus_move, *if_move_plus): New patterns.
(*ifcompare_arith_arith): Simplify the alternatives down to just one,
and split the insn before output.

(*ifcompare_move_not, *ifcompare_not_move): Simplify and split the
insn before output.
(*if_move_not, *if_not_move): New patterns.
(*ifcompare_shift_move, *ifcompare_move_shift): Simplify and split the
insn before output.
(*if_shift_move, *if_move_shift): New patterns.
(*ifcompare_shift_shift): Simplify and split the insn before output.
(*if_shift_shift): New pattern.
(*ifcompare_not_arith, *ifcompare_arith_not): Simplify and split the
insn before output.
(*if_not_arith, *if_arith_not): New patterns.
(*ifcompare_neg_move, *ifcompare_move_neg): Simplify and split the
insn before output.
(*if_neg_move, *if_move_neg): New patterns..
